Many of the hog diseases that have been eradicated from domestic swine, like brucellosis and trichinosis, are fairly common in feral hogs. Here are some safety tips:
-Always wear gloves while butchering and handling meat, it's also advisable to wear eye protection
-Be especially careful around reproductive organs
-Don't eat, drink, smoke, or chew tobacco while butchering or handling hogs or meat
-Cook to a minimum internal temperature of 160 degrees
-If you cut yourself while handling hogs or meat, tell your doctor you could have been exposed to brucellosis. Taking the medicine immediately after potential exposure greatly decreases your chances of contracting the disease. Once you become symptomatic, brucellosis is very difficult to treat and you may forever have recurrences of the symptoms.
They come and go on our lease all the time, we have a creek and wet areas on the lower end of our lease, they stay around there more than anywhere, but even then they still may disappear for a week or two and then suddenly show back up. I think they simply root all the food in a certain area and then have to travel to find more, as far as corn goes, once they find it they will hang around the general area until the corn is gone, so if you want them to stay you have make sure the corn doesn't run out for long.
